okay what you mean by you redid this tank just before 1 week? dose that mean this tank is a new setup?
 
this website may help with the algae http/www.theplantedtank.co.uk/algae.htm
 
but GDA is caused by low co2 and or low nutrients and can be common in new setups best way to get rid of it as i presume its on your front glass just wipe it off with a scraper or clean sponge check the link above for a more in-depth help
 
with regards to your co2, do you have a drop checker inside the tank so you are monitoring the co2, here is a good thread on drop checkers
